Abstract: 639,666. Rotary-hearth furnaces. KEENER, S. F., (trading as SALEM ENGINEERING CO.). July 2, 1947, No. 17493. Convention date, June 7, 1941. [Class 51 (ii)] In a furnace comprising concentric inner and outer side walls spanned by an annular roof, an annular refractory hearth located between the side walls and mounted on a rotatable framework, and annular sand seals spanning clearances between the edges of the hearth and the side walls, the hearth seats on an annular plate which merely rests on the framework, and the latter is located wholly below the side walls and positioned relatively thereto by a system of abutting and radially-adjustable rollers, the troughs of the sand seals being carried on the framework also below wall level and being arranged to receive annular flanges depending from the walls and the crown of the framework. As shown, the furnace structure comprises a roof 12 keyed to inner and outer circular walls 10, 11 which are supported by circular plates 171, 18 and a plurality of columns 19, 20 from beams 17 interconnecting the lower ends of a plurality of circumferentially-disposed buck-stays 14 and 15, the upper ends of the stays being interconnected by tie members 16. The walls 10, 11 are formed with annular shoulders which overlie the edges of an annular hearth 13, 25 supported by a plate 26 which rests on I-section annular beams 33 and channels 34 secured to a framework comprising a plate 32, annular beams 31, channels 30 and radial members 29, the beams 31 carrying journal blocks 35 for rollers 36 running on rails 37. The hearth is thus free to expand and contract without affecting the supporting structure. The plate 26 carries a number of projections 74 which co-operate with the adjacent beam 33 to prevent excessive movement of the hearth. The outer channel 34 supports a flange 47 which dips into a sand trough 42 constructed in sections 43 each detachably mounted by means of brackets 44 on the outer channel 30, the columns 20 supporting a flange 49 which also dips into the trough. A similar sealing arrangement is provided at the inner edge of the hearth. A continuous channel 40 is secured to the inner ends of the members 29 and is engaged by a number of adjustable guide rollers 51 mounted on the columns 19. The outer ends of the members 29 support a channel 41 -secured to which is a channel 58 having a plurality of movable pins 59 extending through its flanges 60. Each pin is encircled by a wear sleeve 61 and forms a tooth for engagement with a driving sprocket 62. The walls 10, 11 are formed with flues 22 and burner ports 21, and the furnace chamber is divided into seven zones by baffle walls 65 and 70 extending downwardly from the roof. These walls are constructed of arches 66, keyed into the side walls, and a lower section formed by refractory brickwork 68 which is filled in between water tubes 67 and the lowermost arch.

Title: Improvements in or relating to textile spinning and twisting apparatus
IPC: D01H1/00
Filed: 1949-07-01
Abstract: 676,016. Sewing-machines. BISHOP, A. O. July 1, 1949, No. 17511/49. Class 112. [Also in Group IX] A device for spinning and twisting yarn, adapted as an attachment to be applied to a sewing machine, comprises a flyer formed of a wire frame 7- 10, the ends 5, 6 of which are secured in a pulley wheel 4 rotatably mounted on a sleeve 3 and driven by a belt tensioned by rollers 34 mounted on a spring frame 35, the sleeve being screwed to a stationary spindle 2. One of the vertical arms 10 of the frame carries a right and left hand internally threaded sleeve 11 rotatable about the arm 10 to move a yarn guide 28 along its length to enable the yarr to be wound along the full length of a bobbin core 16 carried by the spindle 2. The yarn is fed to the guide 8 through guides 27, 25, the guide 25 being attached to a slotted ferrule 15 positioned on the end of the frame and engaging the end of the spindle 2 and contacting the end of the bobbin core 16. A spring 23 is positioned around the ferrule 15 between the end of the frame and a nut 24 screwed on to the ferrule so that by adjusting the nut 24 the pressure exerted by the ferrule on the bobbin core to urge it into contact with a friction washer 22 at its upper end can be varied. The position of the washer 22 can be altered from one between the bobbin core 16 and a pulley wheel 19 which transmits a drive through a pulley rope 20 to the sleeve 11, to a position between the pulley wheel 19 and the sleeve 3. Dogs are provided on the bobbin core, the pulley wheel and sleeve or bobbin core being in direct engagement depending on which alternative position the washer 22 occupies. By rotating the pulley wheel 4 the frame is rotated to twist and wind the yarn on to the bobbin core which is rotated by the pull of the yarn, the rate of rotation being dependent on the friction between the washer 22 and the core 16 or pulley 19, the rate of feed along the core, in the case of the pulley 19 being disconnected from the sleeve 3, also being dependent on the rate of rotation of the core 16. Alternatively the washer 22 may be completely removed whereby engagement of the dogs on the sleeve 3, pulley 19 and core 16 prevent rotation of the core 16. A U-shaped hand appliance may be used for holding two reels of yarns for feeding to the device.

Title: Improved manufacture of quartz and the like articles nonpervious to gases
IPC: C03B19/00
Filed: 1922-06-26
Abstract: 182,781. Deutsch-Englische Quarzschmelze Ges., and Hirschberg, Z. von. June 26, 1922. Forming silica-glass articles.-A method of manufacturing hollow articles of fused quartz, such as dishes, cups, crucibles, consists in producing a tubular blank by the usual methods, cutting the tube into separate small blanks of concavo-convex form, placing the sections upon cores having the shapes of the article to be made, and then submitting the covered cores to the action of a flame having a high temperature, such as an oxy-hydrogen jet. The blanks are caused by the temperature and pressure of the flame to assume the shapes of the core and, at the same time, are glazed so that they become impervious to gases.

Title: Selective tuning mechanism for radio receivers
IPC: G04C23/00
Filed: 1937-06-24
Abstract: 497,490. Electric selective signalling systems. TRIGGS, W. W. (Operadio Manufacturing Co.) June 24, 1937, No. 17579. [Class 40 (i)] A wireless receiver is tuned automatically by means of a shading coil motor, all the coils being energized to brake and stop the drive when the required tuning position has been reached. The invention is described as applied to a receiver which is tuned to different stations at various times of the day, the units which determine the station selected being rotatable cam shafts mounted around the clock dial and any one of five different stations can be selected at any quarter hour of the day. The selecting shafts 92 arranged in apertures 90 around the dial in positions corresponding to the times at which they are effective are turned until the number of the station required at the corresponding time is visible. This rotation moves the station cam 96 into the path of the rotating wipers 100 so that at the appropriate time the cam 96 and the wiper 100 make contact. At the exact quarterhour period spring-set 119 drops into a notch 118 in cam 117, and a circuit is completed for the one pair of shading coils 145, 146 or 147 and 148 of motor A, Fig. 2, so that the motor is energized and drives the condenser shaft of the radio set (through shaft 12) and the sleeve 35 carrying cams 60-65, Fig. 6. These cams have been so set that when each cam engages plunger 20, the receiver is tuned to a wanted station. When the cam 60-65 relating to the wiper 100 engaged by cam 96 engages the plunger 20, a circuit is completed for the other pair of windings of the motor and as the two pairs of windings create opposing torques the movement stops. The circuit of the motor is opened when spring-set 119 is restored by the continuously rotating cam 117. The tuning action is repeated at each quarter hour interval, no movement taking place if the station required is that to which the set is tuned. The sixth cam provides an off position. Switch 49 enables the clock control to be removed so that the set remains tuned to a particular station whilst the motor can be started independently of the clock control by push button 50.

Abstract: 889,249. Photographic film dispensers. EVANS, O. (Powers Chemco Inc.). May 22, 1959, No. 17620/59. Class 98(2). A film dispenser, having a plurality of different film rolls with each of which is associated a feed roller over which the film engages frictionally under a pressure roller, includes means for simultaneously driving all the feed rollers and obtaining through the outlet passage of the dispenser only one film pre-selected by a single manually-controlled knob which, according to its setting, activates cam means associated with each film which lift clear of its feed roll every film but the one selected. Fig. 3 shows in sectional side elevation a light-tight film dispenser housing 18, 22, 26, 24 with outlet channel 38 three film rolls 36 being mounted on shafts 34 supported on brackets 28 fixed to both side-walls of the housing. The film 48 passes over the feed rollers 40 and is held in frictional engagement by gravity-urged roller-shafts 50 supported by arms 52 pivotally secured at 54 to the side walls. The feed rollers 40 are securely mounted on shafts 44 which are journalled to the side-walls, at one side there being a gear train, not shown, to simultaneously rotate all the feed rollers by means of a common drive. At intervals along the length of the feed rollers there are recesses to accommodate a series of finger-like members 56 pivotable on shafts 58 and having lever-extensions 60a by means of which the fingers 56 may be activated by correspondingly spaced cams 62 on shaft 64 to leave their recesses thereby lifting the film and roller 50 out of feeding engagement. When the flat surface 66 of any cam engages the corresponding lever 60a to allow the finger 56 to fall into its recess under gravity, the arrangement is such that the remaining levers are engaged by the arcuate portion of their respective cams so that, as shown by the top and bottom systems of Fig. 3, the levers are turned so as to raise the film. In the 3-film system shown, the cams are in fixed relative angular orientation of 120 degrees. A gear train, not shown, connects all the cams to a single control knob which sets any desired cam into the inactive, or feeding position according to the film required conveniently indicated by indicia on the knob. An indicator mechanism may be geared to the feed-rollers to indicate the length of film dispensed. U.S.A. Specification 2,836,373 is referred to.
